In hot weather, people often use household fans. They are compact, practically silent and create an atmosphere of comfort and comfort. About these devices and will be discussed in the article
What it is?
A small household fan is well delivered in private country house ownership – usually such devices “plunge” to 25 kV. M of useful area. The power of such a home device can reach 50 W. In modern fans that are purchased in specialized stores, there are three speeds, there is also a swivel node that is easily disconnected if necessary. Such aggregates are controlled using the remote control or buttons located on the panel at the base of the device.
There are two main types of cooling devices:
The second option is applied at home more often, as it creates a slight air flow pressure. The impeller of the device may consist of 3 blades, and maybe from 30. The device of such an aggregate is made as follows:
- The blades are attached on the sleeve;
- The sleeve itself is attached to the axis;
- The axis rotates due to the operation of the electric motor to which it is also attached.
The fan when working creates noise background. Dear aggregate works with minimal noise accompaniment. This is achieved by the engine layout and one shaft, where the rotating block with blades is located.
Axial devices There are the following types:
- Reversible – the blades are arranged symmetrically;
- without reverse – the blades are composed asymmetrically.
Also fans differ by the method of manufacturing the impeller.
Reversible fans are aggregates that work in two modes:
- on air exhaust;
- On the influx of air.
Rotation of the blades can be in two different modes. Floor fans are most popular among wide segments of the population. They in a short time cool even big rooms.
The device of the floor fan involves the presence of a leg, which can be adjusted at its discretion. Also there are often designs in which the angle of inclination and corners of turning. These important details make it possible to create optimal modes of blowing and additional comfort.
Floor fans are differentiated into three large subgroups:
Axial devices “with a propeller” are the most common. A blind fan is considered a more advanced device type, because in fact it is a round frame from a metal that is equipped with a working engine. During his work, air masses literally “pushed” into the room. Such models allow you to cool large spaces for the minimum amount of time. Floor fans are often equipped with humidity sensors and air ionizers. They include a device in automatic mode, restoring the microclimate level set in the room. You can also meet sensors that react to the appearance of a person in the room – the fan in this case is turned on automatically.
How to choose?
Buying a fan in the room is not easy, because it requires certain technical knowledge. First of all, you should know exactly what priorities exist, to which attention should be emphasized in the first place. Criterion when choosing an aggregate is its power, because it is the main factor determining the area of ”covering” with cold air. There are also various other priorities that are important to consider with such a purchase.
If a bench-type fan, then its power is not so significant– For such a device, it is primarily important, the size of the blades, as well as silentness in the work. From the last parameter largely depends on its use at night. The level of reproduced noise may vary from 30 to 45 dB. To work at night, the noise level of the fan should not exceed 42 dB. You should also pay attention to the basis of the fixture of the device blades. If the sleeve is present, then noise will be several times more. The presence of ball bearing significantly reduces this indicator, and also increases the service life of the acquired product.
Modern electronic devices currently can be found literally on all household appliances, including fans.
- time indicator;
- Ionization system;
- Temperature and humidity rate.
Without them, of course, you can do, because the main thing – the device must be securely and long work without breakdowns.
Also, when buying it is recommended to pay attention to weight. With an increase in the speed of rotation, the coefficient of unstable equilibrium increases (with the exception of the fans, which are attached to the vertical surfaces). It is not recommended to buy models of unknown trademarks, because in pursuit of cheapness you can purchase a poor-quality product, which in the near future can fail.
Rating the best models
At various trading platforms present hundreds of models of indoor fans – in such a wide range you can get confused. Floor fans are the quietest, so they occupy the top lines of sales.
Mystery MSF-2402. This is an economical, powerful and inexpensive device with a control panel, which is ideal for a country house. Power is 46 W. There are three blades in the device, the height of the appliance rack can be adjusted. Works such an unit at three speeds. If desired, the rotation function can be turned off.
Maxwell MW-3546. This is another popular fan that can be placed on the floor. Different with spectacular view: It has a black color with white splashes. Power is 36 W. In this model, you can adjust the height, angle of rotation, the speed of rotation of the blades. Managed device using buttons.
Model Xiaomi Mi Smart Fan Corresponds to the “Smart Home” format. Managed with a smartphone or personal computer. The unit can be programmed, being away from home, through a special application on a computer.
The device has the following functions:
- Changing audio signals;
- angle of rotation;
- modern design;
- Setting the time mode;
- adjustment of the tilt of the rotating unit from 32 to 125 degrees;
- changing the speed of rotation of the blades;
- Power selection (Network or Battery).
Polaris PSF 3040RC. Popular fan from Premium segment. It is expensive, but enjoys in high demand from users. The power of the unit is 56 W. There are three modes of operation. There are numerous indicators on the panel, which indicate the nature of the device. Advantages of work: you can create a fresh sea wind, the air flow can change every 2-3 seconds, it is also possible a stepwise reduction of the velocity of blowing. Turn to admit to 90 degrees. Managed device from a remote control or using buttons.
How to make it yourself?
The fan is a very simple device, and even a schoolboy will be able to assemble him.
First of all, you should prepare the required working items:
- CDs in the amount of 2 pieces;
- small motor from desktop cooler;
- USB input wire;
- Candle or lighter;
- pencil and ruler;
- Special thermal glue;
- As a block, you can take any cardboard packaging of small sizes.
The advantage of this scheme is that all blocks are at hand. The CD is divided into eight equal parts, it is possible to use geodesic paper or an ordinary school notebook into a cell. Having drawn the figure in the form of a cross, where vertical and horizontal lines are present, each of the angles is differentiated exactly half. Also, such an operation is easy to perform with the help of the transport. As a result, the same figures will turn out to match each other. Plastic is easily cut by a hot knife – it follows it to be carefully so that there are no melted burrs, otherwise you can hurt.
A wine stopper is installed in the hole for better fixation of the element, the joints are processed by glue. With the help of a candle flame, plastic figures should be deformed, a little bending them. Wire with a USB port must be connected to the engine. Polarity is easily changing, therefore, the direction of rotation of the blades changes. Thus, it turned out an improvised propeller to be installed on a rotating axis. Glue allows you to correctly and secure all the design nodes. Time for all the work will leave a little – no more than two hours.
Homemade fan from plastic bottle is pretty simple. There are two variants of this invention. The first is the manufacture of plastic 1.5 l bottles. Motor can be taken from a computer cooler.
The following components will also be required:
- palter battery;
- a piece of foam;
The upper part is cut on the site of the start of the bottle label – it is easier to make a propeller out of it. The billet cuts into six equal shares. The edges of future blades must be reinforced. With the help of a flame, plastic candles can be bent into any direction – it must be done. The blades are attached to the base with the help of a thermal oil, then all the product is satisfied with the rotating axis. The engine is attached to the foam – to make it easy, as the foam cuts without any difficulties. After that, it will only be left to screw the propeller on the plug, which firmly “sits” on the engine.
Possible malfunctions and repair
The purchased device can manifest The following defects:
- The indicator functions, but the engine does not work;
- The indicator does not burn;
- Fan blades do not spin;
- During operation, the device makes a hum;
- The device does not turn on or off.
If the last malfunction occurs, first of all, using the device should be disassembled and checking the power supply – the outlet. It is also recommended to inspect the plug itself – you can violate contacts. If the indicator lights up, the reason may be the failure of the block with the buttons. Then it is necessary to disassemble the block, but the device must be disconnected from the network. Using the tester, you must check the operation of each button alternately. If a button broke, then you can make a connection directly or change this element.
Often fail the speed switches. Using the device they can also be checked and fixable if necessary. In the event that the blades are poorly rotated, the device itself is necessary to disassemble. It is possible to smear the fan engine bearing with machine oil. The case disassembled without any difficulties – is enough to arm a screwdriver and perform a number of manipulations. Fasteners are unscrewed, and the product casing is removed. If the fan stopped moving in different directions, then the blade can be crank – its fastening screws are most likely weakened. In this case, you will need to disassemble the entire device engine housing.
Can spin gears badly in the gearbox – its switch is also recommended to check. All moving elements must be treated with machine oil, then all nodes must be collected.
If the fan makes “incomprehensible” sounds or hum, then there may be several reasons here:
- lack of lubrication;
- the engine does not work well;
- Condenser has failed.
Check follows, first of all, the condenser. Make it easy with tester. The condenser is in the engine block, so the body will have to disassemble. It is also necessary to check the engine – perhaps a malfunction is precisely in it. To do this, the stator should be released from contacts. Resistance must be within 1.21 com. If this is not, the device will get sort, but not work. Under such circumstances, it will be necessary to rewind, but only in the conditions of a specialized repair point, where there are professional equipment.
Sometimes it happens that the plastic blades will deteriorate, and the product begins to make strange sounds.
The deformation can be called:
- exposure to ultraviolet radiation;
- mechanical damage;
- Dropped sleeve.
Make a household fan with your own hands easy. The main thing is to follow the recommendations.
